Application filed August 13, 1912. Serial No. 714,894.

To all whom it may concern Be 1t known that I, FLORA A. BARRETT, a

citizen of the United States, residing at Columbus Grove, in the countyof Putnam, State of Ohio, have invented certain new and usefulImprovements in Detachable Door-Hinges; and I do hereby declare thefollowing to be a full, clear, and exact de scription of the invention,such as will enable others skilled in the art to which it a'ppertains tomake and use the same.

This invention relates to hinges and more particularly to detachablespring hinges specially adapted for screen doors.

Another object is to provide a hinge of this character which may bereadily attached to a door casing or detached therefrom.

Another object is to provide a sectional spring hinge carried by thedoor and adapted to have one portion thereof detachably connected with asecuring member permanently carried by the door casing.

Another object is to generally improve and simplify the construction ofhinges of this type and increase the efiic iency and durability thereof.I

With these and other objects in view my invention will be more fullydescribed and illustrated in the accompanying drawings which showpreferred embodiments of my device and then specificallypointed out inthe appended claim which is attached to and forms a partof thisapplication.

In the drawings :Figure 1 is a front elevation of the upper right handcorner of a door casing and screen door, showing one hinge and partbeing broken away. Fig. 2 is a front elevation of a portion of a doorcasing with a securing member in place, the hinge being removed. Fig. 3is. a sectional view of the line 3-3 Fig. 1. Fig. 4 is a verticalsection on the line H Fig. 1. Fig. 5 is a similar View on the line 5-5Fig. 1. Fig. 6 is a detail view of the hinge removed. Fig. 7 is asimilar View of the securing member removed. Fig. 8 is a detail view ofthe locking key removed.

Referring more specifically to the drawings in which similar referencecharacters designate corresponding parts throughout, 10 designates onesection of the hinge permanently secured along the edge of the door 11by means of suitable screws 12 or other securing members. The hingesection 10 has the upper and lower perforated cars 13 and the verticalrolled portion 14 extendin be tween said ears and slightly spaced herefrom, the purpose of which will presently apear. The oppcsitehingesection 15 has tie spaced hingable slots 16 in its main portion whilethe upper and lower spaced ears 17 are provided near its rolled verticaledge 18 which engages against and rides around the vertical rolledportion 14 of the first section when the two sections are properlyconnected. When said sections are connected, the cars 17 of the secondsection are positioned between the cars 13 and the ends of the verticalrolled portion i l of the first section; the connecting pin 19 ispositioned through the ears of the two sections.

The coiled spring 20 is positioned in the rolled vertical portions ofthe hinge sections and has one end bent to rest upon the main or flatportion of the first section while its opposite end is similarly bent torest upon the main or flat portion of the second seetion, it beingunderstood that the spring is under tension thus acting upon the hingesections to resiliently retain the same in their proper positions.

\Vhen it is desired to hang the door the second section of the hingepresses against the door frame until the parallel arms 21 of the Ushaped securing member 22 project through thehinge openings 16 of saidsec tion. The flat locking key is then passed through the elongatedopenings 21 in said arms thus properly securing said second sectionagainst the door frame 24. It will be understood that the main portionof the U shaped securing member 22 is countersunk in the casing invertical position and fastened in position by means of the countersunkscrews 25, as clearly shown in Fig. 2.

From the foregoing it will be apparent that to remove the door, all thatis necessary is to force the securing keys 23 out of the arms, afterwhich the second section of the hinge may be readily withdrawn, leavingonly the U shaped members 22 upon the casing.

It. will be apparent that that hinge is of such simple construction thatit may be readily and cheaply manufactured and will be highly efficientand effective in use. It will be further evident that minor changes maybe made in the details of construction within the scopev of the appendedclaim without departing from the spirit of my invention.
